FIELD OF THE INVENTION

The present invention relates to imaging systems or vision systems for vehicles.

BACKGROUND OF THE INVENTION

Use of imaging sensors in vehicle imaging systems is common and known. Examples of such known systems are described in U.S. Pat. Nos. 5,949,331; 5,670,935 and/or 5,550,677, which are hereby incorporated herein by reference in their entireties.

SUMMARY OF THE INVENTION

The present invention provides a vision system or imaging system for a vehicle that utilizes one or more cameras to capture images exterior of the vehicle, and provides the communication/data signals, including camera data or image data that may be displayed or processed to provide the desired display images and/or processing and control, depending on the particular application of the camera and vision or imaging system. The present invention provides a touch screen or user input that allows the driver of the vehicle to selectively adjust the displayed images, such as to adjust the virtual viewing angle or viewing point or to zoom or pan the image, in order to provide the desired displayed images to the driver for the particular driving condition or scenario.

According to an aspect of the present invention, a vehicle vision system includes a plurality of cameras at the vehicle and having exterior fields of view (such as forwardly, rearwardly and sidewardly of the vehicle) and a display screen for displaying images captured by the cameras, such as in a top view or surround view format (where the images are merged or synthesized to provide a single composite display image from a virtual viewing angle). The system includes a control that is operable to adjust the virtual viewing point or virtual viewing angle or the degree of zoom or degree of panning or the like of the displayed images to provide a desired or appropriate display to the driver of the vehicle to assist the driver of the vehicle during a particular driving maneuver or operation. The control is responsive to a touch screen or a gesture interface or touch sensitive user input that detects a touch or approach of a driver's finger (either gloved or non-gloved) and allows the driver to adjust the displayed images by touching and/or moving one or more fingers at the touch screen to at least one of zoom or pan or adjust a virtual viewing point or adjust a virtual viewing angle or the like. The touch screen may have actuators for applying a haptic feedback to the driver's touch inputs.

These and other objects, advantages, purposes and features of the present invention will become apparent upon review of the following specification in conjunction with the drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

A driver assist system and/or vision system and/or object detection system and/or alert system may operate to capture images exterior of the vehicle and process the captured image data to detect objects at or near the vehicle and in the predicted path of the vehicle, such as to assist a driver of the vehicle in maneuvering the vehicle in a rearward direction. The object detection may utilize detection and analysis of moving vectors representative of objects detected in the field of view of the vehicle camera, in order to determine which detected objects are objects of interest to the driver of the vehicle, such as when the driver of the vehicle undertakes a reversing maneuver.

Referring now to the drawings and the illustrative embodiments depicted therein, a vehicle 10 includes an imaging system or vision system 12 that includes one or more imaging sensors or cameras (such as a rearward facing imaging sensor or camera 14 a and/or a forwardly facing camera 14 b at the front (or at the windshield) of the vehicle, and/or a sidewardly/rearwardly facing camera 14 c, 14 b at the sides of the vehicle), which capture images exterior of the vehicle, with the cameras having a lens for focusing images at or onto an imaging array or imaging plane of the camera (FIG. 1). The vision system 12 is operable to process image data captured by the cameras and may provide displayed images at a display device 16 for viewing by the driver of the vehicle. Optionally, the vision system may process image data to detect objects, such as objects to the rear of the subject or equipped vehicle during a reversing maneuver, or such as approaching or following vehicles or vehicles at a side lane adjacent to the subject or equipped vehicle or the like.

Driver assistant vehicle vision systems featuring virtual top views are known (such as described in U.S. Pat. No. 7,161,616 and/or PCT Application No. PCT/US10/25545, filed Feb. 26, 2010 and published on Sep. 2, 2010 as International Publication No. WO 2010/099416, and/or PCT Application No. PCT/US10/47256, filed Aug. 31, 2010 and published Mar. 10, 2011 as International Publication No. WO 2011/028686, and/or PCT Application No. PCT/US11/62834, filed Dec. 1, 2011 and published Jun. 7, 2012 as International Publication No. WO 2012-075250, and/or PCT Application No. PCT/US2012/048800, filed Jul. 30, 2012, and published on Feb. 7, 2013 as International Publication No. WO 2013/019707, and/or PCT Application No. PCT/CA2012/000378, filed Apr. 25, 2012, and published Nov. 1, 2012 as International Publication No. WO 2012/145822, and/or PCT Application No. PCT/US2012/064980, filed Nov. 14, 2012, and published May 23, 2013 as International Publication No. WO 2013/074604, and/or PCT Application No. PCT/US2012/068331, filed Dec. 7, 2012, and published Jun. 13, 2013 as International Publication No. WO 2013/086249, and/or U.S. patent application Ser. No. 13/333,337, filed Dec. 21, 2011, now U.S. Pat. No. 9,264,672, and/or U.S. provisional application Ser. No. 61/613,651, filed Mar. 21, 2012, and/or German Publication Nos. DE102009025205A1 and DE102010010912A1, and/or European Publication No. EP000002136346A2, which are all hereby incorporated herein by reference in their entireties). Such top view systems are used for assisting the driver while backing up the vehicle, filling in blind spots for safe turning of the vehicle and/or the like.

It is known to generate a top view by synthesizing images captured by multiple vehicle incorporated cameras in a bowl like shape (such as described in U.S. Pat. No. 7,161,616, such as at FIG. 33 and FIG. 50 of U.S. Pat. No. 7,161,616). It is also known to use different z-x angles of the virtual viewpoint looking at the car body (such as described in U.S. Pat. No. 7,161,616, such as at FIGS. 20A-20D of U.S. Pat. No. 7,161,616), and/or to have a view from the top (z direction) to specific sections (such as described in German Publication No. DE102009025205A1, such as at FIG. 4, and/or U.S. Pat. No. 7,161,616, such as at FIG. 27D of U.S. Pat. No. 7,161,616) and/or having virtual view point highs (z-direction), such as described in U.S. Pat. No. 7,161,616, such as at FIGS. 19A-19F of U.S. Pat. No. 7,161,616).

The system described in U.S. Pat. No. 7,161,616, provides or includes preselected virtual viewpoints which mappings are precalculated and stored in look up tables. All virtual viewpoint angles are tilted in a x-z angle, no angles other than 0 degrees are provided into y-direction. Views onto other preselected regions beside the center of the vehicle body are disclosed in German Publication No. DE102009025205A1, but there is no tilt angle in the y-direction involved, just a shift of the virtual viewpoint in x-y-z direction.

Procedures for adapting the virtual projection plane according the virtual viewpoint's elevation for receiving plausible projection views are also described in PCT Application No. PCT/US2012/048110, filed Jul. 25, 2012, and published on Jan. 31, 2013 as International Publication No. WO 2013/016409, which is hereby incorporated herein by reference in its entirety.

Overlays and highlighting of hazards around the vehicle are also described in German Publication No. DE102010010912A1 and/or U.S. Pat. No. 7,161,616, which are hereby incorporated by reference in their entireties.

Receiving remote destination data, particularly parking spot coordinates is described in European Publication No. EP000002136346A2. The disclosure of EP000002136346A2 does not reveal any intention or method for judging the feasibility or quality of the pointed parking spots. There may be gaps which are big enough in the size, but still not relevant to consider, due to areas where parking is prohibited or impossible.

Motion parallax (or parallax scrolling) is a natural optical effect. It can be used artificially when trying to give a more or less flat scene a depth view impression comparable to a stage having flat paper coulisses in the foreground and background of a scene play. More technically, but in a similar manner, this effect can be used in computer games (see, for example, http://en.wikipedia.org/wiki/Parallax_scrolling). Such parallax scrolling is a special scrolling technique typically used in computer graphics, wherein background images move by the camera slower than foreground images, creating an illusion of depth in a 2D video game and adding to the immersion. See also, the short video at ‘http://www.youtube.com/watch?v=Jd3-eiid-Uw’, which shows a so called ‘fake 3D’ effect based on motion parallax under synchronization to the viewer's head or eye movement. For such a fake 3D effect, an appliance is required for tracking the head of the watching person. On conventional single 2D display systems just one person can enjoy the fake 3D effect at a time. Parallax mapping (see, for example, http://en.wikipedia.org/wiki/Parallax_mapping), which is also referred to as offset mapping or virtual displacement mapping, is an enhancement of the bump mapping or normal mapping techniques applied to textures in 3D rendering applications such as video games.

In vehicle systems, a vision system may be operable to track the driver's eye, such as for determining a gaze direction or determining drowsiness of the driver. For example, systems are used for detecting the driver's drowsiness are disclosed in U.S. Publication No. US-2005-0163383 (which is hereby incorporated herein by reference in its entirety), and systems for controlling airbag deployment are disclosed in U.S. Publication No. US-2004-0085448 (which is hereby incorporated herein by reference in its entirety), or a vision system may adjust the view or alignment on head up display overlays to the outside scene, or may control airbag deployment or control a camera and/or illumination source of the vehicle (such as described in U.S. Pat. No. 7,914,187, which is hereby incorporated herein by reference in its entirety) and/or the like.

Also, German Publication No. DE102009009047A1 (which is hereby incorporated herein by reference in its entirety) describes how a three dimensional (3D) scene can become segmented into two dimensional (2D) layers coulisses (so called 2D Imposters) positioned in different distances for a collision avoidance system, and this is meant for machine vision (data processing of image data) and not for human vision (displayed on a display screen for viewing by the driver of a vehicle). Later referred 2D imposters are known from computer games (see, for example, http://www.gamasutra.com/view/feature/2501/dynamic_2d_imposters_a_simple_.php).

Driver assistant vision system virtual cameras are typically not independent in position and angle. The driver typically cannot control the virtual viewing position freely and easy. To suit all driving or environmental conditions, especially to show all hazards, the virtual view position and direction should be independent, preferably selectable in x-y-z height and tilt angle by the driver or automatically by the vision system control, in order to always provide the best view according the current condition. The virtual viewpoint should be intuitively steerable. The present invention provides a useful improvement to such vision systems, such as the system described in European Publication No. EP000002136346A2, incorporated above, in conjunction with vision system virtual cameras control.

The present invention provides a system that uses depth segmented 2D layer coulisses (2D imposters), such as described in DE102009009047A1, incorporated above, to provide a fake-3D effect in a vehicular surround view vision system based on tracking of finger and/or hand movement at or proximate a touch screen or touch sensitive device and/or tracking of the driver's head and accordingly motion parallax scrolling of the virtual view point.

Referring now to the drawings, the following provides a description of the driver assist system of the present invention:

(1) Instead of using pre-calculated mapping tables, the mappings of the virtual view become calculated in real time.

(2) Instead of providing a fully vertical top view on situations, hazards become provided within a close up or centering (maybe split) screen, and flexible, preferably freely or manually positionable views from an x-y-z angle come into use. Optionally, the system may capture images of one or more than one hazard at a time (see FIG. 2).

(3) The close up or centering itself draws the driver's attention to the hazard. The hazards may also become highlighted by overlays (see image 4 in FIG. 2) or by color change.

(4) The virtual viewpoint may be altered by gestures, such as hand gestures or finger gestures or the like. The gestures may be detected by suitable gesture sensing devices such as, for example (one, several or in combination):

-   -   a. Time of Flight sensor (as like PMD from PMD-Technologies®);     -   b. Stereo camera disparity detection;     -   c. Mono camera with pseudo stereo via motion disparity         detection;     -   d. Structured light sensor (as like Microsoft Kinect®); and/or     -   e. Touch screen or touch sensitive device or proximity sensor.

The detection devices may be installed inside the passenger compartment at a position suitable to detect the driver's gestures at most or all times, preferably integrated to the center glove compartment, the top light column or the central mirror mounting area. By utilizing an image-based or non-touch based gesture detection device, the gesture detection device may detect the gestures of a gloved hand as well as a non-gloved hand. Optionally, a touch sensitive device or proximity sensor may be utilized to detect and discern hand gestures by the driver of the vehicle, and optionally the touch sensitive device or proximity sensor may be operable to detect touch or proximity of a gloved hand or finger or fingers as well as a non-gloved or covered hand or finger or fingers.

The system may be operable to detect and discern various gestures and may associate various individually discernible gestures with various operations. For example, the system may detect and discern the following gestures for switching camera modes and controlling the camera and its viewpoint:

-   -   ‘CHOOSE’ or ‘PICK’ or ‘ENTER’ (mode/control/enter functional         group/sub function);     -   ‘ABORT’ mode;     -   ‘RECENTER’ viewpoint;     -   ‘RECALIBRATE’ viewpoint;     -   ‘REALIGN’ viewpoint;     -   ‘TRAVERSING’ (sideward) shifting viewpoint;     -   ‘CHANGING viewpoint's HEIGHT’;     -   ‘CLOSING UP’ viewpoint;     -   ‘DEPARTING’ viewpoint;     -   ‘NICKING VERTICAL’ viewing angle;     -   ‘NICKING LATERAL’ viewing angle;     -   ‘ROL’ view;     -   ‘TILT’ view;     -   ‘LOCK’ entry; and/or     -   ‘UNLOCK’ entry     -   (description similar as referred in (4)).

‘LOCK’ entry may be performed by a turning gesture of the right hand while having the index finger and the thumb closed (see, for example, FIG. 9C), exemplifying the turning of a key inside a key hole such as like shown in FIG. 9D. The ‘LOCK’ entry may function comparable to key pad lock functions on cell phones, here for gestures entries (not necessarily limited to automotive vision camera application). As soon as a user enters a gesture LOCK command, any subsequent or following gestures entered willingly or by mistake (use case) may be ignored except the ‘UNLOCK’ command or alternatively the system may be “unlocked” by a conventional (physically) button entry or speech command (known art speech command acknowledgement). The present invention thus provides two dimensional menus that are controllable by just three gestures:

-   -   ‘UP-DOWN’—rolling the menu downwards; such as, for example, by         whipping from rearward to forward or vice versa;     -   ‘LEFT-RIGHT’—rolling the menu sidewards; such as, for example,         by whipping from the right to the left or vice versa;     -   ‘PICK’—for picking a choice; such as, for example, by closing         the index finger and thumb finger tips (such as shown in FIG.         9D) or by moving the index finger downwards or tapping, such as         like when clicking a computer mouse.

One dimension may be the (choice of one) general functional group as like:

-   -   Viewing driver assistant system;     -   Radio;     -   Navigation;     -   Phone;     -   Internet;     -   Heating, Ventilation, Air Conditioning System, Seat heating;     -   Seat position (actuator) control;     -   Window lifter control; and/or     -   Openers (Roof top/tilt window control, trunk actuator control,         fuel lid and/or the like).

The second dimension may be the (choice of one) specific feature that changes when wiping to an orthogonal direction then the general functional group dimension (see FIG. 9E) as like:

-   -   Sound volume (under the functional group ‘Radio’); such as, for         example, becoming louder to the right;     -   Phone functions (under the functional group ‘Phone’); such as,         for example, giving the choices one by one when whipping from         left to the right:         -   Pick up;         -   Dial/Redial;         -   Phone Contacts;         -   Forward phone;         -   Configure.     -   Virtual Top View Camera (under the functional group ‘Viewing         driver assistant system’); such as, for example, giving the         choices one by one when whipping from left to the right:         -   Most recent hazard view;         -   Second recent hazard view (when whipping up down up after             entering ‘Most recent Hazard view’);         -   Third recent hazard view;         -   Chase view (from the virtual rear);         -   Side view;         -   Free virtual camera view.

For example, after ‘PICK’-ing the ‘Free virtual camera view’, the system may offer a control mode for the virtual camera which can be used intuitively by the driver. It may perform as like laying the right hand onto a globe's top surface. When emphasizing to role the hand forward or sideward, the virtual camera is set up to copy that rolling simultaneously (or in a scaled ratio) such as in the manner shown in FIG. 9B. By using the ‘PICK’ gesture (closing the index finger and thumb finger tips such as like shown in FIG. 9C) while moving the hand, the viewing angle may stay fixed but the virtual camera may move transversal forward, sideward and vertically. Opening the index finger and thumb finger tips while moving the hand downward may comprise the earlier mentioned ‘CLOSING UP viewpoint’ gesture. When the user carries out this gesture the virtual view may zoom up. The opposite ‘DEPARTING’ viewpoint gesture may effect a de-zooming.

(5) The virtual viewpoint may become altered by sliding and tapping or tipping on a touch screen.

-   -   a. The slides may follow an intuitive logic.     -   b. One, two and/or three finger slides and tapping action are         dedicated to specific vision control groups:         -   i. Tapping may be dedicated as a ‘CHOOSE’, ‘ENTER’, ‘ABORT’             or ‘RECENTER’ or ‘RECALIBRATE’ or ‘REALIGN’.             -   1. The realigning function may automatically turn the                 virtual view back to the vehicle's body and turns the                 views top upright.         -   ii. Sliding two fingers (mostly) horizontal may be dedicated             as viewpoint ‘TRAVERSING’. The virtual view point moves side             wards, without changing the viewing angle.         -   iii. Sliding two fingers (mostly) vertical might be             dedicated as ‘CHANGING viewpoint HEIGHT’.             -   1. Functions (ii) and (iii) may alternatively behave                 slightly different by fixing the aiming point that the                 virtual view looks at. The virtual view point turns in                 all three angles while TRAVERSING side wards or in                 HEIGHT or both.         -   iv. Sliding two fingers (mostly) away from each other be             dedicated as ‘CLOSING UP’ (or Zooming in, but zooming is not             fully identical to rolling a camera, and rolling is             preferred). The virtual view point is rolling towards the             aiming point looking at. The position changes, but not the             viewing angle.         -   v. Sliding two fingers (mostly) in direction of one another             be dedicated as ‘DEPARTING’. The virtual view point is             rolling away (or De-Zoom) from the aiming point looking at.             The position changes, but not the viewing angle.         -   vi. Sliding one finger (mostly) vertical may be dedicated as             changing the viewpoint's ‘NICKING’ (vertical) angle.         -   vii. Sliding one finger (mostly) horizontal may be dedicated             as changing the viewpoint's ‘LATERAL’ angle.             -   1. NICKING and LATERAL angles may be combined to ‘ROL’                 which serves both functions at the same time with one                 finger. The virtual view changes the viewing angle, but                 not the position during this function.             -   2. The ROL(-ing) function may come with a behavior as if                 the rolling view has a kind of inertial mass and                 friction, so the already rolling view continues rolling                 in the same direction with decreasing speed when taking                 the sliding finger tips off the touch screen.         -   viii. Sliding one finger around another might be dedicated             to ‘TILT’ the virtual view side wards (the third degree of             freedom beside NICKING and LATERAL turning).

(6) Referring now to FIGS. 9F-H, the gesture interface may work in combination to physically present keys or keys projected onto a surface or a capacitive sensor key pad as another aspect of the invention and optionally utilizing the later referred haptical interface comprising incorporated pad or needle actuators or the like. When the user is closing (such as, for example, to within about 2 cm) to a key pad or key area or the like (any of above mentioned types), the projection illumination or backlight illumination may increase simultaneously or may change color, or its shape may changes, or projected lines may increase in size or the key may increase in size or pop out (or pop out more) as like attracted from the user's closing finger (see FIGS. 9F and 9G). This provides the user the feedback that his or her intention is acknowledged. When striking and/or when lifting the button the key may change its projection illumination, or backlight illumination, such as, for example, a short flickering or inverting or turning on the center or may change color (again), or projected lines may decrease or increase in size or the key may decrease in size or pop in (as later referred, compare FIGS. 3F and 3G) or its shape may change as like rounding up the edges (more)(see FIG. 9H). After releasing the key, its effect may fade out slowly (such as over about two seconds or thereabouts) to its normal state.

(7) When increasing the distance of the virtual view from the vehicle, by raising the viewpoints highs or distance, the scene captured by the vehicle's cameras is limited, so the more distant area must become filled.

-   -   a. This may happen by using image data of remote image providing         facilities or vehicles connected by any kind of remote         communication channel, or     -   b. by using historical image data, stored earlier, when passing         the scene which is to project, or     -   c. by using image data out of a street and/or satellite view         database like ‘GOOGLE STREET VIEW’™ and/or ‘GOOGLE EARTH’™ or         the like.         -   i. This kind of top view departure and/or approach may be             performed automatically . . .             -   1 . . . when turning on or switching of the vision                 system as a start up/end up animation or . . .             -   2 . . . in conjunction with navigation mapping to                 provide the actual vehicle's position onto a map (maybe                 relatively in a distance to a destination spot).                 -   a. Also a camera side and/or top view of the parking                     spot scene may be provided and also a time stamp of                     when the spot was detected (see FIG. 12).                 -   b. To determine whether the host vehicle is fitting                     into the optional parking spot, there may be a ‘park                     box’ overlayed to the parking spot scene, which has                     the same size that the host vehicle would take                     within that scene. The box may be semi transparent                     and may be adapted according to the virtual distance                     (such as shown in FIG. 16B). Additionally, the                     parking spot dimensions may be displayed as numbers                     as an additional overlay. Mismatching may be                     highlighted (such as in a selected color, such as                     red, and/or such as by flashing or blinking, and/or                     such as via hatched borderline bars of the park box                     and/or the text overlay). The park box may appear                     automatically or may be selectively triggered by the                     user, preferably by a touch onto a touch screen in                     the vehicle.                 -   c. The gap may become rated in a best choice                     algorithm of elapsed time to when the parking gap                     was spotted, a degree of difficulty to reach the                     gap, a walking distance to destination, a driving                     distance to parking gap, a criminal or accident                     focus, a child safety when departing, a POI, parking                     costs, and/or the like.         -   ii. This kind of top view departing and/or closing may be             controlled automatically or manually, such as via a user             input or the like controlled by the driver or occupant of             the vehicle.

(8) Optionally, the virtual viewpoint may become shifted according the driver's head movement.

-   -   a. The driver's head and/or eyes may be tracked by a         surveillance system, which is preferably within the vehicle         compartment, preferably fixed vis-à-vis the driver.         -   i. Optionally, the driver surveillance system may comprise a             camera based system.             -   1. The camera may use any suitable image algorithm that                 is capable to discriminate the position and distance of                 the driver's head and/or eyes relative to the camera.             -   2. The camera may operate within visible light, and                 optionally, and desirably, within invisible wave                 lengths, such as infrared light wavelengths and/or near                 infrared light wavelengths.             -   3. The system may include an active light source to                 illuminate the driver's contours so the surveillance                 system receives enough contrast to operate. Optionally,                 and desirably, the light source may comprise one or more                 infrared or near infrared light emitting light emitting                 diodes (LEDs).         -   ii. Optionally, the driver surveillance system may comprise             a LASER based system.             -   1. The LASER may actively scan a surveillance area in                 which the driver's head is typically found or located                 and/or may track the driver's head. An algorithm may                 form a cloud of scan point data, which may be processed                 in a manner where typical body markers are discriminated                 so these can be tracked, which enables the system to                 determine the driver's head position and distance                 relative to the LASER source.     -   b. The tracked driver's head position in relation to the         position of the camera or LASER or sensor may be brought on         according to the display's position by any suitable trajectory         algorithm of the vision system.     -   c. At the time the driver moves his or her head, the virtual         vision view point will be shifted accordingly. Due to correct         parallax scrolling (fake 3D) such as from computer games, the         depth segmented 2D layer coulisses known from DE102009009047A1         for machine vision (also known as ‘2D imposters’ known from         computer games) become virtually shifted accordingly within the         inventive automotive human vision embodiment. Accordingly, the         fake 3D vision image on the display shifts over the display         responsive to the driver's head movement.     -   d. The present invention thus turns dynamic 2D imposters         orthogonal to the user's view, such as by using aspects of         computer games.     -   e. In DE102009009047A1, the imposters layers are arranged in         parallel lines of distances. The present invention provides a         panoramic vehicle vision system that arranges the distance lines         (layers/shells) of the imposters circumferential, onion-like         shell around the virtual view point (equates to the virtual         projector) so that the user always faces the surfaces orthogonal         to the user's point of view (the user's head).     -   f. When raising the view point, the imposters tilt (bend) to the         back still showing their front to the viewer.         -   i. The lower end may turn in a curved shape towards the             center when the view point is raised.     -   g. According to the rules for having motion parallax at times         when the virtual view point is shifting forward (x direction)         (compare to FIGS. 24A to 24C) the 2D imposters move against the         viewer. The close imposters move further and respectively faster         as compared to the imposters in the background. The imposters in         front move less than those at the side. The imposter may grow in         size when they approach and shrink when they get more distant.         The behavior is accordingly opposite when moving virtually away.         These effects more or less apply when the view is mostly in a         horizontal angle (x-z pane).         -   i. For economic reasons (including the processing load of             the control or microprocessor), the imposter's size and             mappings may not change continuously but may change in steps             according to the distance and angle.         -   ii. The mappings may be simplified by not projecting the             captured (and maybe transformed) images from the vision             system's cameras itself than simplified symbols (such as a             car, a person, a dog, a tree, a shopping cart, and/or the             like). The symbols mappings may be offline calculated and             stored in a look up table for every angle and size which is             desired for use in the vision system.     -   h. The present invention thus provides a system that is operable         to scroll the mappings on the 2D imposters surfaces according         the viewing angle the driver is looking at. This is different to         ‘parallax occlusion mapping’ also known from the computer game         area (see, for example,         http://en.wikipedia.org/wiki/Parallax_occlusion_mapping; and/or         http://www.youtube.com/watch?v=gcAsJdo7dME&feature=related).         Such parallax occlusion mapping is used to procedurally create         3D definition in textured surfaces, by using a displacement map         (similar to a topography map) instead of through the generation         of new geometry.     -   i. The present invention thus provides a vehicle vision system         that uses ‘parallax occlusion mapping’ effects on high         performance systems.     -   j. The present invention thus provides a vehicle vision system         that uses ‘parallax mapping’ (or ‘parallax shading’) effects         known from computer games (see, for example,         http://en.wikipedia.org/wiki/Parallax_mapping), which may         require less processor capacity than ‘parallax occlusion         mapping’ (‘parallax mapping’ is faking shades onto where virtual         gaps would be depending of the virtual light source's direction,         and ‘occlusion mapping’ is additionally virtually hiding         structures/profiles in the background which should become hidden         by structures/profiles in the foreground but still just maps all         that onto a flat projection surface, not calculating geometries         of the structure/profile itself, and ‘parallax occlusion         mapping’ requires more calculation power than ‘parallax         shading’).

With reference to the drawings, FIG. 19 is a schematically illustration of 2D imposter which are set up in horizontal lines, with the horizontal shells having the same distance. The lines on the horizon appear closer to each other than the closer ones due to the slightly elevated viewing angle. In the illustrated embodiment, all imposter shells have the same height, with the more distant ones appearing smaller than the close ones. In this example, no real scenes are mapped (projected) by the virtual projector to the imposters surfaces. In the illustrated embodiment, the use is for human visualization. Such a vision system may utilize aspects described in DE102009009047A1, incorporated above, such as for machine vision purposes.

FIG. 20 is an illustration of the same scenery as in FIG. 19, with the view being elevated so that the viewing angle is now substantially or fully vertical. In cases where the imposters do not turn toward the viewer but stand upright, such as shown in FIG. 20, the (projected mapping) surfaces are not visible any more. The top view is more important for driver assistance vision systems than flat viewing angles.

FIG. 21 is different from FIGS. 19 and 20, and the virtual view point is identical to the virtual projector position and direction (typically in automotive human vision systems). To avoid that the projection pane, so the imposters turn out of the view when the virtual view point (and the projector) become elevated, the present invention (in vehicle vision) provides that imposters are bent back in a way that the surface always stays orthogonal or substantially orthogonal to the viewer (projector). As shown in FIG. 21, the example has the lower end of the imposter bent in at an edge. Such a system may utilize aspects of the systems described in PCT Application No. PCT/US2012/048110, filed Jul. 25, 2012, and published on Jan. 31, 2013 as International Publication No. WO 2013/016409, which is hereby incorporated herein by reference in its entirety, where it is disclosed that a 2D vision system may bend down fully enveloping bowl shape like projection panes, such as when the virtual view point becomes increasingly elevated. In the illustrated embodiment of FIG. 21, the projection pane is divided up in several projection panes, having different distances (see also FIG. 19).

FIG. 22 is identical to FIG. 21 with the exception that imposter or at least the lower end becomes smoothly turned instead of a sharp edge. This may improve the appearance of the transitions from bottom projections to vertical objects projections. FIG. 23A illustrates a human captured by the visions system camera(s) as a relevant object is being projected onto a (single) imposter. The virtual view point is slightly elevated looking down in FIG. 23A, while FIG. 23B shows the virtual view point after it has been risen (either by manual input, automated by the system or because the viewer has elevated his viewing angle by rising his head which was captured by head/eye tracking). The virtual projection pane (the imposter) has been bent down further to stay orthogonal. The mapped (projected) image of the human might have been altered according parallax shading. Additionally, occlusion mapping might have use in the system of the present invention. FIG. 23C shows that the virtual view point has been risen further in comparison to FIGS. 23A and 23B, such that the virtual projection pane (the imposter) has been bent down to nearly horizontal. The projection (mapping) may show the captured human more as like looking from overhead than from the front. Parallax shading and/or occlusion mapping may also find use in this situation.

FIG. 24A illustrates that the system of the present invention may arrange imposters or distance lines or layers of the imposters circumferentially around the view point (such as like layers of an onion) so as to always face the surfaces orthogonally to the user's view point or the user's head. This is different from what is shown in FIG. 19, which arranges the imposters in parallel lines of distances. The scenery shown in FIG. 24A is in the condition of to according to the timestamps of FIG. 24B (before move).

FIG. 24B is an illustration of the 3D parallax effect in accordance with the present invention. At times when the virtual view point is shifting forward (such as in the x direction), and as can be seen with reference to FIGS. 24A and 24C, the 2D imposters move relative to the viewer. The close imposter moves further and respectively faster as the imposters in the background, and the ones in front move less than those at the side. The imposter may grow when they advance and shrink when they get more distant. In the illustrated example, the virtual move forward may be manually controlled by a touch screen sliding command (such as discussed above and such as shown in FIG. 7), but may also or otherwise be automated by the system or may move because the viewer has moved his or her head forward and this movement was captured by a head/eye tracking system which controls the scenery movement online in all three dimension to provide the 3D parallax effect to the viewer within the 2D display. The to timestamp is the timestamp of beginning the movement and the ti timestamp is the timestamp after movement or at the finish of the movement. FIG. 24C illustrates the scenery in the condition of the time ti of FIG. 24B (after movement or after completion of the movement).

An entry area or preferably the (flexible) screen (underneath) may incorporate pad or needle actuators which preferably act in an orthogonal direction for providing an active haptic feedback to inputs of the driver or to actively form structural content that is haptically perceptible or conceptual such as the likes of (soft-) buttons or borderlines. The haptic feedback input may comprise any suitable haptic feedback, such as, for example, a “popping in” or depression of a soft button surface such as shown in FIGS. 3D and 3E. The structural area may comprise one or several actuators. The haptic conceivable embossed structure may also be capable of virtually moving over the screen, such as in the form of a transverse wave or the like, by employing actuator needles in the direct neighborhood or region at which the embossed structure shell virtually moves while releasing actuators in the back end of the virtual structure. Examples of haptic feedback systems and actuators are disclosed in U.S. Publication No. US-2009-0244017, German Pat. No. DE102004037644, and International Publication No. WO 2009/117632 (which are hereby incorporated herein by reference in their entireties).

In the present inventions a solution of the actuator materials is provided. There are three materials within the range of choice:

-   -   Electroactive Polymers (EAPs);     -   (Electro-)Pneumatic Artificial Muscles (E-PAMs);     -   Carbon Nanotube Muscles (CNMs); and/or     -   Embedded coils.

An EAP named Vivitouch® (distributed by Artificial Muscle Inc.) is suggested to become used in vehicle control panels and mobile computing on their website: http://www.artificialmuscle.com/technology.php.

The present invention may utilize (E-)PAMs to actuate single needle (-like) actuators, such as shown in FIGS. 3F and 3G, or in pad (-like) actuators, such as shown in FIGS. 3B and 3C. For reaching a feasible longitudinal actuation range (such as about 1 mm or thereabouts) and/or force, the (E-)PAMs may be packed into a stack.

As soon as the feedback actuator density reaches a comparably high level, the touchable structures can become displayed in the haptic sense. In the example shown in FIG. 3F, a soft button or touch region is structurally formed by the haptic (feedback) actuator needles, such that the button emerges out of the level of its surroundings within the pad. In this way, the touch region or button is haptically experienceable and discernible. As a reaction to a touch detection at the soft button's surface, and such as shown in FIG. 3F, the button's structure may be changed to an inverted structure. Such an inverted structure may feel to the user as if the button popped in or depressed by the applied touching force.

When using embedded coils, a force outward or inward can be applied in the region of one coil pair such as can be seen in FIGS. 3D and 3E. The material of region (4) may be relatively stiff (lightest gray) compared to the material in region (3), which enables a limited elastic popping in or out of the area of the inner coil. When applying a static current, the magnetic field with the strength B (μ×H) of the inner coil acts orthogonal to the magnetic field with another the strength B of the outer coil which causes a transversal force from one coil to the other. Since the inner coil area is movable within the elastically material's limits it becomes pressed outward counter wise the immobile outer coil. By applying an AC current a vibration can be generated. The coils may be printed to a foil in front (of a stiff display) or behind or integrated (in an elastic display) or onto a dedicated touch area. The coils may have several layers (FIG. 25) or may be integrated to a PCB (FIG. 26), such as like with Faltflex® produced by \Mirth Elektronik GmbH & Co. KG, Germany. Alternatively to having a pair of coils there may be just one coil surrounding an area having a high permeable particles as like ferrites (μ_(r):=4.15000) or diamagnetic particles as like Copper (0≤μ_(r)<1) both for resulting the inner area tending to escape the inducting magnetic field, applying a force outward. The particles may become printed sputtered onto or molded into the carrying (partially elastic) substrate.

When using EAPs or CNMs, the actuator pad may consist of actuator strings set up in a meshwork in which the strings are weaved into one another in a primarily two dimensional extension. FIG. 3H shows an example according to the present invention that has a touch screen actuator pad utilizing CNMs actuator strings set up in a staggered meshwork when no muscle actuation is controlled. As shown in FIG. 3H, the gray colored muscle strings B act horizontally and the black colored muscle strings A act vertically. The fixation points C of the muscle sections are where the muscle sections are fixed or attached at or to the screen.

To apply force at a specific spot, the strings (both the horizontal and the vertical strings) in a direct neighborhood or region are controlled in concert (see FIG. 3I). When actuated, the actuators shorten, in that way the fixation points become pulled towards one another. As shown in FIGS. 3I and 3J, when the muscles in region D are controlled to actuation, the screen bends outbound in that region. As best shown in FIG. 3J, the screen E bends outbound or outward generally orthogonal to the A-B plane in that region. A force F is applied in that orthogonal direction. In the schematic of FIG. 3J, the screen's surface is implied or shown as a grid E, but it would comprise a continuous surface in an actual embodiment, and the fixation points are shown at C, with the horizontal actuator strings B shown as dark gray and the vertical actuator strings A shown as light gray.

When actuated, the screen material flexes or pops out or protrudes (see FIG. 3J) or applies a force in the orthogonal direction to the actuator strings. When popping out is inhibited (such as, for example, when a finger of a user sets on that spot of the screen), the applied force, by a reaction (in force) by the screen, becomes receptivable or perceptible or discernible to the user. The actuator strings of the screen of the present invention are preferably staggered relative to one another, which enables the screen's outbounding force to be applied equally, such as is shown schematically in FIGS. 3H-J.

Therefore, the present invention provides a vehicle vision system that allows a user to manually select and control the display of a top down or surround view image or images to provide a desired view at the display of the vehicle, such as to assist the driver of the vehicle in reversing the vehicle or parking the vehicle or the like. The vision system includes a touch screen that is accessible and usable by the driver of the vehicle to adjust the displayed images (such as a virtual view point, virtual viewing angle, pan, zoom and/or the like) to provide a desired view to the driver of the vehicle. The vision system may provide information from other vehicle vision systems or other information sources, such as parking space information and the like, to assist the driver of the vehicle in finding an empty parking space and parking the vehicle in that space. Some of the information may be displayed or provided to the driver automatically. The vehicle vision system of the present invention thus provides enhanced display of information and images to the driver of the vehicle based on images captured by a plurality of cameras or image sensors of the vehicle and having exterior fields of view, such as forwardly, rearwardly and sidewardly of the vehicle.

The system includes an image processor operable to process image data captured by the camera or cameras, such as for detecting objects or other vehicles or pedestrians or the like in the field of view of one or more of the cameras. For example, the image processor may comprise an EyeQ2 or EyeQ3 image processing chip available from Mobileye Vision Technologies Ltd. of Jerusalem, Israel, and may include object detection software (such as the types described in U.S. Pat. Nos. 7,855,755; 7,720,580 and/or 7,038,577, which are hereby incorporated herein by reference in their entireties), and may analyze image data to detect vehicles and/or other objects. Responsive to such image processing, and when an object or other vehicle is detected, the system may generate an alert to the driver of the vehicle and/or may generate an overlay at the displayed image to highlight or enhance display of the detected object or vehicle, in order to enhance the driver's awareness of the detected object or vehicle or hazardous condition during a driving maneuver of the equipped vehicle.

The camera or imager or imaging sensor may comprise any suitable camera or imager or sensor. Optionally, the camera may comprise a “smart camera” that includes the imaging sensor array and associated circuitry and image processing circuitry and electrical connectors and the like as part of a camera module, such as by utilizing aspects of the vision systems described in PCT Application No. PCT/US2012/066571, filed Nov. 27, 2012, and published on Jun. 6, 2013 as International Publication No. WO 2013/081985, which is hereby incorporated herein by reference in its entirety.

The vehicle may include any type of sensor or sensors, such as imaging sensors or radar sensors or lidar sensors or ultrasonic sensors or the like. The imaging sensor or camera may capture image data for image processing and may comprise any suitable camera or sensing device, such as, for example, an array of a plurality of photosensor elements arranged in at least about 640 columns and 480 rows (at least about a 640×480 imaging array), with a respective lens focusing images onto respective portions of the array. The photosensor array may comprise a plurality of photosensor elements arranged in a photosensor array having rows and columns. The logic and control circuit of the imaging sensor may function in any known manner, and the image processing and algorithmic processing may comprise any suitable means for processing the images and/or image data. For example, the vision system and/or processing and/or camera and/or circuitry may utilize aspects described in U.S. Pat.
